Frequently asked questions
FAQThis sunscreen contains chemical UV filters (avobenzone, homosalate, octocrylene, octisalate) which some healthcare providers recommend avoiding during pregnancy and breastfeeding due to potential hormonal effects. While evidence is limited, many experts suggest using mineral sunscreens (zinc oxide or titanium dioxide) during this time as a precaution. Always consult your healthcare provider for personalized advice.
No, this sunscreen is NOT safe for fungal acne-prone skin. It contains sunflower oil (Helianthus Annuus Oil) and raspberry seed oil (Rubus Idaeus Oil), which have fatty acids in the C12-C24 range that can feed malassezia yeast. If you have fungal acne, look for sunscreens without these oils or choose mineral options.
Yes! This sunscreen is compatible with most active ingredients. In fact, using SPF is essential when using retinol, AHAs, or BHAs as they can increase sun sensitivity. Apply your actives first (morning for vitamin C, evening for retinol), let them absorb, then apply this sunscreen as the final step of your morning routine.
This sunscreen works well for most skin types, especially oily and combination skin due to its lightweight, non-greasy gel texture. It's also excellent for those with medium to deep skin tones who struggle with white cast from other sunscreens. Dry skin types may want to layer a hydrating moisturizer underneath. NOT recommended for fungal acne-prone skin.
UV protection is immediate upon application. For skincare benefits from the antioxidants (vitamin C, niacinamide, green tea), you may notice improved skin condition within 1-2 weeks and more even skin tone after 4+ weeks of consistent daily use. The primary benefit of sunscreen is prevention of future sun damage, which is cumulative over time.
Apply this sunscreen as the LAST step of your morning skincare routine, after cleanser, toner, serum, and moisturizer. Wait 15 minutes before sun exposure for protection to develop. It can also serve as your makeup primer - just let it absorb fully before applying foundation or other makeup products.
This sunscreen has a low comedogenic rating of 1/5. It's formulated with non-comedogenic polymers and lightweight emollients that are unlikely to clog pores. The formula also contains niacinamide which helps control sebum and minimize pores. However, everyone's skin is different, so patch testing is recommended if you're prone to breakouts.
This sunscreen has a 12-month PAO (Period After Opening). Store it at room temperature away from direct sunlight and heat. Sunscreen effectiveness can degrade over time, so it's important to use it within this timeframe and check for any changes in texture, smell, or color before use.
Verdict: Allies of Skin The One SPF 50 Invisible Sunscreen Gel delivers on its promise of truly invisible, high-level sun protection. The PA++++ rating, 80-minute water resistance, and antioxidant-rich formula make it a premium choice for daily wear. It excels as both a sunscreen and makeup primer, with a texture that disappears into all skin tones without a trace. While the price point is steep and it's not suitable for pregnant women or those with fungal acne, it's an excellent investment for anyone seeking cosmetically elegant protection with skincare benefits. Best suited for those who prioritize invisible finish and are willing to pay for quality.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
